The only differences between several pressure gauges would be how much pressure they measure. All of them measure vacuum.

How to find the air pressure in the gap of a pop can?
May 13th, 2011 — monitorspulseblood Pressure
In a pop can, there is usually a small gap between the actual soda and the can. With only the basic science equipments (ex: graduated cylinder, beaker, weighing scale), how could the air pressure in the gap be found?
The second answer is good with one exception. Shaking the can of a carbonated beverage does increase the pressure inside. The carbon dioxide that was in solution as carbonic/carbolic acid is no longer in solution, so occupies a greater volume. that alone is sometimes enough to burst the can. Another way to tell is to squeeze a plastic bottle of carbonated soda. then, shake it and squeeze it again. It's much more rigid.
Mmmm, thats difficult. if the can is shaken, the pressure changes. (CO2 is difficult that way).
To measure the volume, open the can and pour a liquid in the opening from a graduated cylinder (or similar) until the can is full. Measure the remaining contents of the graduated cylinder.
Need help with density of gasses. How does atomic mass, pressure and volume affect it?

I need some help with a science project.
How does pressure affect the density of a gas?
How does volume affect the density of a gas?
How does atomic mass affect the density of a gas?
Please and thank you =)

The more pressure you put on a gas, the more it will compress the particles into a smaller volume. Therefore, the density would increase.
If you decrease the volume, the density will increase. if you increase the volume, the density will decrease.
The greater the mass, the greater the density if the volume remains constant.
Increase Pressure <==> Decrease Volume <==> Increase Density.
The Density of a gas is dependent upon its Atomic mass.
Atomic or Mol. mass of a gas can't be changed (except as an isotope).
Different gases have different atomic mass. Hydrogen (H2) is the lightest gas and has the lowest density.
As gases become 'heavier' i.e…CH4, < N2, < O2..< etc.. they have increasing densities, and increasing mol. mass.
